One end of the plurality of hydraulic lines 28 are connected to the plurality of joysticks 24 and the plurality of hydraulic treadles 26.
A hydraulic pressure line 102 and a hydraulic return line 104 of a hydraulic pump 100 are connected to an input of a hydraulic circuit block 36. The hydraulic pump 100 distributes hydraulic fluid to the plurality of hydraulic joysticks 24 and hydraulic treadles 26 through the hydraulic circuit block 36. The plurality of quick disconnect adapters 36 are threadably engaged with the plate member 32 on one side thereof. The plurality of threaded adapters 38 are threadably engaged with the plurality of quick disconnect adapters 36 on an opposing side of the plate member 32. A plurality of hydraulic pressure sensors 34 are threaded into the plurality of threaded adapters 38. Hydraulic pressure in the joysticks 24 and foot treadles 26 hydraulic lines 28 are measured by the plurality of hydraulic pressure sensors 34. An electrical output from each hydraulic pressure sensor 34 is connected to the cab bridge controller 20. The electrical bulkhead 18 includes a signal socket 42 and a power socket 44. A signal cable 46 includes a bulkhead plug 48 extending from one end and a controller plug 50 extending from an opposing end. The bulkhead plug 48 is plugged into the signal socket 42 and the controller plug 50 is plugged into the cab bridge controller 20 for transfer of electrical signals from the cab member 10 to the cab bridge controller 20. A vehicle controller 45 is preferably used to receive electrical signals from a button panel 47. The vehicle controller 45 is also used to display information to an operator display 49. The vehicle controller 45 is also connected to the cab bridge controller 20 through electrical bulkhead 18.
An output from the cab bridge controller 20 is connected to the cab transceiver 22. The cab bridge controller 20 converts the electrical signals from the plurality of hydraulic sensors 34 and the vehicle controller 45 into a suitable form for wireless transmission. The cab transceiver 22 transmits the plurality of electrical signals from the plurality of hydraulic pressure sensors 34 and electrical signals from the signal socket 42 to a frame transceiver 52. The frame transceiver sends the electrical signals to a frame bridge controller 53, which in turn sends electrical signals, which control hydraulic proportioning valves in an electrical to hydraulic valve block 55. A power cable 54 includes a generator plug 56 on one end and a power plug 58 on an opposing end. The generator plug 58 is plugged into an electrical generator 106 and the power plug 56 is plugged into the power socket 44. With the hydraulic pump 100 and the electric generator 106 connections, the modular hydraulic cab 1 is capable of operating remotely with a modular hydraulic frame 2 through wireless communication.
The docking station 12 may be used to provide a physical foundation and an operational base for the modular hydraulic cab 1. The docking station 12 includes a base member 60, the hydraulic pump 100 and the electrical generator 106. The base member 60 includes a support base 62 and at least two upright mounting members 64. The at least two upright mounting members 64 extend upward from the support base 62. At least one threaded tap or hole is formed through a top of each upright mounting member 64 to receive a retention bolt inserted through a floor 15 of the cab enclosure 14. The hydraulic sensor plate 16, cab bridge controller 20 and the cab transceiver 22 are preferably retained on the support base 62. The hydraulic pump 100 and the electrical generator 106 are attached to a top surface of the support base 62. With reference to FIG. 6 , the hydraulic pump 100 is connected to the hydraulic pressure line 102 and the hydraulic return line 104. The electrical generator 106 is connected to the electrical bulkhead 18 through the power cable 46. The docking station 12 enables the hydraulic modular cab 1 to remotely operate from and wireless with the modular hydraulic frame 2.
However, modular hydraulic cab 1 does not have to be used with the docking station 12. The hydraulic pump 100 and the electrical generator 106 may be connected to the modular hydraulic cab 1 from any other suitable source, besides the docking station 12. The hydraulic sensor plate 16, the cab bridge controller 20 and the cab transceiver 22 would be physically retained on the modular hydraulic cab 1 and not on the docking device 12.
A diagnostic device 66 may be connected to the cab bridge controller 20 through a wired connection to monitor hydraulic pressures of the joysticks 24 and foot treadles 26, and status of the buttons of the button panel 47. A diagnostic device 68 may be connected to the cab bridge controller 20 through a wireless connection.
While particular embodiments of the invention have been shown and described, it will be obvious to those skilled in the art that changes and modifications may be made without departing from the invention in its broader aspects, and therefore, the aim in the appended claims is to cover all such changes and modifications as fall within the true spirit and scope of the invention.
